１５ｄ头低位卧床时心率变异的功率诺和时序分析在航天和地面模拟失重实验（如卧床）中，常常发现心率是增加的。但至今对心率增加的产生机理尚有不同看法。一种认为是由于迷走紧张度升高引起的；另一种则认为是由于交感紧张度的升高引起的。本实验的目的是通过１５ｄ卧床...
Power Novo and Timing Analysis of Heart Rate Variability at 15d Low Bed Rest During heart rate and ground simulated weightlessness experiments (such as bed rest), it is often found that heart rate is increased. But so far there is a different view on the mechanism of heart rate increase. One is thought to be due to increased vagal tension; the other is due to the rise of sympathetic tone. The purpose of this experiment is 15d bed ...
